DIRIGIBLE l-EADLIGIIT Application filed .August 31, 1927. Serial No'. 218-56157.

rIhis invention relates to headlights and `particularly to a headlight that may be turned on its support as the vehicle turns.

One object of the invention is that it may be readily attached to a locomotive or vehicle of the ordinary construction.

Another advantage is that the parts may eas-ily be lept in repair and wear taken up by tightening certain bolts usedin the con.

struction of theinvention.

Vith these and other objects as will appear as the description proceeds, I will now proceed to describe the invention in connection with the drawings in which:

Figure l is a side view of the invention as attached to a locomotive.

Fig.` 2 is a side sectional view of my invention.

Fig. 3 is a view of a male supporting member.

Fig. 4 is a view of a female supporting member.

Fig. 5 is a view of the upper rotating arm shown in section in Fig. 2.

Fig. Gis a detail view of another arm shown in section in the upper part of Fig. 2.

Fig. 7 is a view of a lower arm shown in the lower part of Fig. 2, and7 Fig. 8 is a View of the bracket shown at the lower part of Fig. 2.

l represents a headlight casing which, as best shown in Fig. 2, is bolted to a male member or base 2 by bolts 3 with their heads countersunhf in the member 2. 4: is a female base member into the upper surface of which a flange 5 of the male member is fitted. 6 is a pivot for the casing l which may be welded or otherwise rigidly attached to the casing so that when the pivot member 6 is rotated as i0 hereinafter described it will rotate with it the casing l of the headlight enclosed therein and the male member 2 attached thereto. 7 is a braclet which may be attached to the front 4of the locomotive as indicated in Fig. 4-5 1 and has integral with it an arm 8 through which a rod 9 passes. Attached to the top end of the rod 9 is an arm 10 having therein a. slot 1l near its left hand end as shown in Figs. 2 and 6. Rigidly attached to the pivot 5U member 6 at its lower end is another arm 12 having vertical bolt hol-es 13 spaced apart nea-r its left hand end as shoivnY in Figs. 2 and 5,. through which a bolt 14e may passA with its lower end resting in the slot 1I of the arm below.. The object off having". a plurality of holes 13 is to adjust the bolt 14- at various; diistaarces from the pivot member 6i in order to get the proper amount of turning motion of the headlight.

The female member 4 may be bolted to@ an arm. 17 of the bracket 7 and I preferably provide a coilar 18 around the pivot member 6" between the arm. I2 and the arm 17 of the bracket 7.

To take up any wear in the parts I provide bolt holes: 19`Y in the arm 12 withbolts' therethrough which may be tightened `oceasionally so asto firmly hold the bolt M and the pivot member 6 soA that as' the arm 12 is rotated hereinafter described, it will causev the pivot member 6 to rotate and thus turn the headlight as desired. A similar bolt hole' 2()A with a suitable bolt therein is useful for keeping the arm l0 securely clamped tol the rod 9.

When the headlight is` applied toy a locomotive as shown in Figs.. l and 2, I prefer:- ably bolt a collar 2l to a" suitable support on the: top of a truck through which the rod 9Y passes and thence through a hole in the' top of the truck down to an arm 22 fastened securely to the bottom of the rod 9 and lie-pt. tight around the rod 9 by a boit 23- passed through a bolt hole 24e and to lreep the bolt 23-tight7 I may provide a vertical bolt 25 passing through a bolt hole 26y in the arm 22. In the left hand end of the arm 22 I provide a boit hole 27 through which a bolt 28- passes and exten-ds through a slot 30 ifn abraclet 3l hel-d to a portion of the truck 32 of a locomotive. The bracket 31 may be bolted to the member 32 of the truck by bolts 35.

In order to hold the bolt 28- tightly in the arm 22, I provide a bolt 37 passing through a bolt hole 38.

It will be clear from the foregoing that Ythe truck comes to a curve and its direction chan-ged. theV bracket 3l will operate through the bolt 28 and arm 22 to turn the rod 9 and SCF through its arm the bolt 14 and the arm 12 to turn the pivot member 6 which being rigidly fastened to the headlight casing l w1ll cause the latter to turn and turn the i light.

The depression in the female member 4 may be supplied with oil to relieve the -friction between the female member 4 and the male member 2.

10 Whenever the parts become loose by reason of wear, by tightening up the bolts in the arms l2 and 22, the lost motion may be taken up and the arms kept tight around the pivot member 6 and the rod 9. It will thus be 15 seen that I have provided a headlight that will turn with the truck and wherein the lost motion may be taken up and the parts kept in working order, and the invention may be easily applied to the ordinary locomotive without material change in the existing device.

Having described my invention, what I claim as new is:

1. Operating mechanism for a headlight comprising a casing, a pivoted member rigidly attached to the casing, an arm rigidly attached to said pivoted member and having a plurality of vertical bolt holes therein, a two part extensible rod having pivotal connection with a locomotive truck frame and carrying an upper and lower arm with means for taking up lost motion between the rod and arms, a pin in the lower arm, a projection on the truck and a slot connection between said projection on the truck and said pin said upper arm having a slot adapted to receive a pin inserted in either of said vertical bolt holes in the arm carried by the pivoted member.

0 2. A headlight operating mechanism comprising a headlight casing, a support consisting of a bracket having an upper and lower arm extending outwardly from said support, the upper arm of the bracket supporting said 46 casing, a male member secured to the bottom of the casing, a cooperating female member secured to the upper arm of the support, a pivot member rigidly attached to the center of the bottom of the headlight casing and 50 passing downwardly through the centers of both said male and female members, a rod with upper and lower arms detaehably and adjustably clamped to said rod, means to take up lost motion between both said arms and said rod` said rod being journaled in said lower arm of said bracket, an arm attached to said pivot member and having a series of holes therein, a pin adapted to fit in said holes, said upper arm having a slot therein to receive said pins when inserted in either hole anda bracket attached to a truck and having a pin and slot connection with the lower arm on said rod. i

In testimony whereof I aflix my signature.
